PENCIL-CASE.

Specification of Letters Patent. Patented Dec, 31, 1912,

Application filed January 24, 1912. Serial No. 673,143.

T 0- all whom it may concern:

Be it known that we, GEORGE V. ORBAN and BOGUMIL SILBERsrEIN, subjectsof Hungary and Austria, respectively, residing at New York 'city, in thecounty of New York and State of New York, have invented certain new anduseful Improvements in Pencil-Cases,' of which the following is aspecifica-tion.

Our invention relates toimproved penci cases, and more particularly tocases of thi character wherein provision is made fo the expedientfeeding of the lead.

One of the objects of the invention is to provide a pencil case in whichthe lead feeding mechanism is extremely simple and composed of but fewparts, so'as to minimize the likelihood of the device becomingdisarranged, and to render the manipulation of the mechanism more easy.

To the accomplishment of the recited objects and others coordinatetherewith,- the preferred embodiment of my invention resides in thatconstruction and arrangement of parts hereinafter described, illustratedin the accompanying drawings, and embracedings for a detail descriptionof our invention, the numeral 5 designates a sheath, formed of anysuitable material and provided with a longitudinal bore, as 6, extendingfrom one end to a point just beyond the center of the sheath. This bore6 is adapted to receive a small coil spring 7, aplun ger 8, and ametallic sleeve 9. The plunger 8 is provided at its inner terminal withan enlarged head, as 10, which engages the outer end of said spring,while the shank of said plunger projects into the bore 11 of the sleeve9, the latter being split longitudinally at diametrically oppositepoints, as at 12, on its rear extremity to present bifurcations ofsubstantially arcuate cross section which diverge slightly in thedirection of slotted at 13, only at a plurality of points, and thepieces of metal bet-ween the slots converge outwardly. The -rear end ofthe sheath is formed with a longitudinally disposed bore 14 and with athreaded extension 15 adapted to receive a cap as seen in Fig. 1. Thisbore or chamber 14 serves as a receptacle for extra leads.

In assembling the component parts of the device, the spring is firstinserted into the ends of the bore 6. A suitable length of lead is thenintroduced into the bore 1 of the sleeve through the inner end thereof.The diameter of the bore is such that when the sleeve is held in avertical position with its outer terminal pointing downwardly, the leadwill gravitate til it reaches the convergin ends of the metal betweenthe slots 13, WhlCh present a diameter somewhat less than the diameterof the lead, and consequently normally prevent the lead from protruding, or maintain the same in an inactive position. The plunger 8 .issubsequently clamping action of the. metal intermediate the slots 13,and constrains the lead 13, outwardly to the desired active position,asexhibited' in Fig. 1 of the drawings. In this connection, thedivergent rear ends of the sleeve frictionally engage the walls of thebore 6 so as to effectively resist the expansive force of the coilspring 7 and at the same time permit of the sleeve being constrained thelead.

In Figs. 4 and 5 we have shown a slight modification of the device,wherein the sheath 5 is divided into two sections, 17 and 18, connectedat their inner ends by means of the complemental screw threads 19. Theouter extremity of each section, 17 and 18, is equipped with the samemechanism hereinbefore described and thus presents a double pencil case.At the junction of the sections a small bore, as 20, is formed forcontainin extra leads. 1

n conjunction with the modified form of our invention, we prefer to usethe construction and arrangement of caps exhibited in Fig. 5 of thedrawings, the same comprisinwardly when occasion requires feeding of Itshould be understood that in its broader aspect the inventioncomprehends the employment not only of the various means described, butof equivalent means for performing the recited functions.

While the arrangement shown is thought at the present time to bepreferable, itis desired to reserve the right to effect suchmodifications and variations thereof as may come fairly within the scopeof the appended claims.

What is claimed, is z- I 1. A pencil case comprising a sheath having abore therein, a lead holder fitted within said bore and having its innerend longitudinally slitted and its outer end slotted with the rnaterialbetween the slots converging, and a plunger within the bore of the leadholder and means acting on said plunger to overcome the clamping actionof the outer end of the lead holder, said holder being inwardly movableWithin the sheath to force the lead outward.

2. The pencil case herein described. the same comprising a sheath havinga longitudinal bore, a sleeve having its outer end slotted and formedwith lead grasping members and its inner end longitudinally slit withthe bifurcations divergingin the direction of the length of the sleeve,a plunger within the sheath projecting into said sleeve, and a springwithin the sheath acting upon said plunger to force the lead outward,said GEORGE V. @RBAN.
